Question

Which of the following features play a role in reducing water loss in Pinus?

• A. Sunken stomata
• B. Thick cuticle
• C. Needle like leaves
• D. All of these

Answer 1

The correct option is D All of these

Pinus is a gymnosperm. The leaves in gymnosperms are well adapted to withstand the extremes of temperature. Presence of sunken stomata (not freely exposed to the atmosphere), thick cuticle (reduces loss of water by diffusion from the top cells of the leaves) and needle-like leaves (reduced surface area exposed to the atmosphere) play an important role in reducing water loss.
